Application filed March 7,

My present invention has reference to steaminjector gas burners particularly designed tor cooking and heating stoves but applicable a so for boiler and other furnaces.

The primary object of the invention is the provision of a burner by whose use gas and atmospheric air are initially introduced into a chamber and partly mixed therein, and further introduced into a second chamber where the fuel is ignited, the ignited fuel being brought against a battle plate in the ,ast mentioned chamber and from which battle plate the burner tube extends and in which last mentioned chamber thereis a valve controlled steam injector pipe that directs the flame through the burner tube and the adjustment of the valve in the said injector pipe regulates the flow of mixing gas and air and the flow of the flame through the burner tube, and likewise insures a pertect combustion.

To the attainment of the foregoing the invention consists in the improvement as hereinafter described and definitely claimed.

In the drawings:

Figure 1 is an approximately central longitudinal sectional view through a gas burner in accordance with this invention.

Figure 2 is a sectional View on the line 2-2 of Figure 1, looking in the direction of the arrows.

In the drawings, the numeral 1 designates a tube. This tube is wholly open at one end but has arranged therein a disc 2 that provides a battle plate. This disc is disposed a greater distance away from the open end of the tube than from the partially closed end thereof. Screwed in and closing the partially open end 3 of the tube there is a nipple 1. This nipple has its outer end closed but there is extended through the said closed end and secured thereto an air conducting pipe 5. The pipe 5 terminates a slight but suitable distance away from the partially closed end 3 ot the tube 1.

lhe angle branch of the nipple 4 has screwed therein a gas conducting pipe 6.

The partially closed end 3 ofthc tube 1 is provided with an annular series of angularly disposed air inlet openings 7, and the chamber 8 provided between the end 3 and the battle plate 2 has side and bottom air inlet openings, each of which is surrounded by an inwardly directed short pipe member 9.

Screwed in the gas conducting pipe 6 there is a comparatively small pipe or tube 10 GAS BURNER.

whose passage is regulated by a hand controlled valve 11 and this pipe 1.0 has an angle branch 12 directed toward the lower opening that is surrounded. by the short pipe 9 in the chamber 8. It is to be noted by reference to the drawings that the pipe section 12, which provides the burner end of pipe 10 does not enter the short pipe or tube 9, and consequently does not interfere with the free passage of air through the said short pipe.

Let through the pipe 1 and entering the chamber 8 there is a steam conducting pipe 13. This pipe has an angle or nozzle end 14 that is arranged centrally with respect to the opening 15 in the battle plate 2. The

steam conducting pipe has the passage therethrough controlled by a hand operated. valve 16. (ias flowing through the pipe 6, above the small pipe or tube 10 will be received in the space 17 between the nipple 4t and the air inlet pipe 5 and will circulate in this space. This gas, before entering the charm her 8 will be contacted by and mixed with the air that flows through the air inlet pipe 5.

Atmospheric air is also introduced through the openings 7 in the end 3 of the tube 1 and likewise through the openings surrounded by the short pipes 9. The burner end 12 of the pipe 10 is ignited to light the gases in the chamber 8 and the valve 16 is opened so that steam is injected through the nozzle end 14: 01. the said pipe into the burner end 18 of the tube 1.

With my in'iprovement it will be noted that the air and gas is caused to thoroughly cominingle before the ignition thereof and that the vaporized steam injected through the opening 15 in the battle plate 2 will directthe flame through such opening and outward through the burner 18 of the tube 1. It is also to be noted that the injector draws air through the inlet openings in the burner and by regulating the said valve the intensity of the flame and the force thereof may be likewise regulated.

Having described the invention, I claim:

A gas burner including a tube having one of its ends partly closed and its other open, the said partly closed end being provided with air inlet openings, a disc-like bailie plate in the tube, providing an air mixing co1npartn'ient between the partially closed end and said battle plate, said compartment having side and bottom openings therethrough and short pipes extending into the chamber and surrounding said openings, a

, nected with the gas pipe and having a burner end disposed slightly below and in a line with the lower opening in the mentioned chamber, and a valve controlled steam in- 10 jector having its nozzle end disposed in a line with the opening in the bafile plate, all

as and for the purpose set forth.

In testimony whereof I afi'ix my signature.

BERT THORNTON.
